Stupid Simple Acne Protocol

Stop buying random skincare products. Start following a system.

Acne skincare doesn't need to be complicated.

The Stupid Simple Acne Protocol breaks acne care down into an evidence-based routine built around four core products — plus an optional fifth step if you need it.

No 10-step routine.
No constantly switching products.
No guessing whether something is actually working.

Just a straightforward plan you can consistently follow.

Inside the guide:

• The Four-Product Rule — the core routine and why each product is there
• How to tell the six types of acne lesions apart, and which ones a topical physically can't reach
• The difference between acne vulgaris, "hormonal" acne, and fungal acne — and why the third one isn't acne at all
• What actually causes breakouts, from androgens and your cycle to sweat, friction, and stress
• Exactly how to build your morning and evening routine
• Affordable over-the-counter product recommendations
• How to introduce adapalene without wrecking your skin barrier
• When and how to add benzoyl peroxide
• What to expect during the first 12 weeks
• How to track progress with photos that actually tell you something
• What you can buy over the counter versus what needs a prescription
• When over-the-counter treatment has hit its ceiling and it's time to see a dermatologist

The philosophy is simple:

Use the right products.
Use them correctly.
Give them enough time to work.
Don't constantly change the plan.

The routine takes roughly 90 seconds twice a day and can be built for around $50 with budget product choices.

You don't need a bathroom counter full of products. You need a routine you can actually stick to.
